IMPROVEMENT IN LAMPS.

Specieation forming part of Letters Patent No. 37,690, dated February17, 1863.

To all whom it may concern:

Be it known that I, ALBERT N. HENDER- SON, of Bu'alo, county ot' Erie,and State of New York, have invented a certain new and useful ,Improvementin Lamps and l do hereby declare the following to be a full,clear, and exact description thereof, reference heilig had to theannexed drawings, making part ot' this specification, wherein- Figure 1is a perspective view of my lamp, and Fig. 2 a vertical section of myburner.

The object of my invention is to produce a chelp lamp that Will burnkerosene and kindred oils without a chimney, without smoke, and withoutunpleasant odor, as it consumes all the gas escaping from the oil.

C represents the body of the lamp, which may be made of any suitablematerial. Bis a wick-tube, made in the ordinary way. This wick-tube Isurround by another similar tube of larger size, A, so as to leave aspace, with out ascending air-currents, all around the wick-tube of thefourth of an inch, (more or less, according to the size of the lamp,) atthe bottom of which I make small holes in the top ot the lamp. Thislarger tube, A, is titted into a socket, E, in the top of the lamp, sothat said tube may be sunk to a level with the top ot' the wick-tube, orelevated a little above it, at pleasure.

I have found by repeated experiments that any surplus gas or oil emittedfrom the Wick sinks into the vacant space D, thus isolated between thesetubes, and thence through the small holes into the body ofthe lamp,except what rises into and is consumed by the lame, which at its basespreads out to the edge of the outer tube, and thus envelops andconsumes gradually all the gas that rises from said isolated vacantspace between the tubes. Thus I make a cheap lamp that gives a bright,clear ame without a chimney, economizing oil and consuming all smoke,gas, or unpleasant odor.

What I claim as my invention, and desire to secure by Letters Patent,is-

The combination ot' the said larger tube around the said wick-tube, soas to afford the said space without air holes between them, inconnection with the said small holes connecting said space with theinterior of the body of the lamp in the manner and for the purposes setforth.

In witness whereof I hereto set my hand this 3d day of February, A. D.1863.

ALBERT N.. HENDERSON.
